讲座题目：Knowledge: gift or burden of innovation?

摘要：The accumulation of knowledge is crucial for the development of scientific innovation. However, in recent years, despite a significant increase in the volume of research in both academia and industry, there has been a noticeable decline in breakthrough innovations. Some studies suggest that the accumulation of knowledge leads to increased learning costs, prolonging the innovation process, promoting teamwork, and narrowing individual research fields. In contrast,others argue that the innovation process essentially involves the recombination of existing knowledge,  thereby suggesting that knowledge accumulation can accelerate innovation. This paper examines the role of knowledge accumulation in the innovation process by distinguishing between the accumulation of general field knowledge and the specific knowledge directly referenced in individual innovations. Through a theoretical model following Arora et al.（2021）, this paper discusses how knowledge accumulation can reduce innovation costs, while directly referencing existing knowledge increases the difficulty of innovation. Knowledge accumulation encourages citations, which exhibits a substitute effect with citations in the innovation cost, thereby mitigating the negative impact of citations on innovation. Additionally, by utilizing data compiled by Park et al.（2023） and NBER Patent Project data, this paper provides empirical evidence showing that field and subfield level knowledge reserves promote both innovation and citations, whereas direct citations constrain innovation. Thus,the observed decline in innovation is more attributable to citation behavior rather than to the accumulation of knowledge.
